Distinguish all-drive native absence from read uncertainty and confirm current pool targets before omitting a recovered name. Cover both existing single-pool writer lock domains, release before encoding or output, and preserve cache terminal errors without blocking the HTTP error response on remote publication.
Keep ordinary entries free of recovery I/O and locks. Bound the selective short lock-conflict wait, preserve existing retry intervals and quorum, and make retries cancelable with late-grant cleanup coverage. Restore the original raw listing callback and unchanged scanner/healing/migration callers now that recovery errors originate in the merger.
Add deterministic deletion, pool ordering, cache, lock-routing and cancellation regressions to race CI. Focused cmd/dsync/lsync race suites and verifiers pass; complete current-main integration and bare-binary performance validation are recorded in PR #239.

Capture the metacache peer before launching cleanup and pass listing
options by value. The parent can clear its cache ID without changing the
background RPC lookup or racing with its reads of shared request state.
Publish complete immutable disk snapshots through atomic.Value in the
listing fixtures instead of replacing getDisks after requests start.
Add a real peer RPC regression for cleanup using the original cache ID;
reverting the options copy reproduces both the race and an empty RPC ID.
Verified the final 18-test listing race suite, 30 repetitions of the real
peer regression, formatting checks and make lint. Prior runtime evidence
retains its original e90cb206 source identity.

Continue PR #221 while retaining its original commits and authorship.
Route latest-only fallback reads through the namespace lock used by normal
writes, propagate terminal scan errors before cache completion, and retain
delete markers until the cross-pool merge has resolved them.
Recount narrowly eligible latest null-version metadata when mixed erasure
layouts prevent selection. Keep each EC group separate and preserve the
requested quorum, strict resolution, and version-listing behavior.
Add regression coverage for locking, terminal errors, cache completion,
delete markers, mixed EC layouts, and HTTP behavior; run focused race tests
in CI. Verified with make test, focused race tests, and local distributed
single- and multi-pool rolling-restart workloads with exact final oracles.
